Abstract

The present invention relates to a method for downlink power control in the base station of a code division multiple access (CDMA) communication system. The total assigned downlink power from the base station is adjusted to a maximum downlink power level by means of individually adjusting the assigned bit rates of an appropriately selected subset of downlink channels to those users having a data communication connection. Said subset is retrieved by applying suitable selection criterions for the downlink channel, e.g., the momentarily assigned bit rate, the reported pathloss, or the user subscription type.
